    When mounting large loads at high altitude, for example when mounting blades on wind turbines, a lifting tool (8) is often used in which the blade is placed during lifting and mounting of the blade on the mill's hub. However, sometimes situations where displacement of the center of mass between loaded and unloaded lifting tool (2) will necessitate displacement of the lifting point of the lifting tool before lifting bracket (2) is released from the blade, so that the crane's main wire (6) must be repositioned to be vertical again. However, it can be relatively difficult to ascertain the orientation of the main wire, which is why a lifting bracket (8) is provided, comprising a flat-like body (14) with a first through-going outlet (16) configured to receive a portion (17) of a first connecting link (19). ) connected to the main wire (6) and a second through-going outlet (18) configured to receive part of another connecting link on the load (2, 4), characterized in that the second through-out outlet (18) comprises a spherical bearing (22) configured to receive the second connector, and the flat-like body (14) adjacent the spherical bearing (22) comprises a measuring instrument (26) with signal sensor (28) for recording the angle (A) between the lifting wire (6) and the vertical, where the signal transducer (28) is configured to transmit a signal containing measurement results for visualization on an external unit (30) with a screen (31) for visualization, located at the crane driver and / or at the crane ns supervisor.

    The present invention relates to a ceiling bracket for mounting the main wire on a crane and a suspended load, where the main wire's discharge axis is defined as the Y axis and a plane winding wire on the Y axis is defined by the X axis and Z axis respectively. , wherein the ceiling bracket comprises a flat-like member having a first throughput configured to receive a portion of a first connecting outlet staring in connection with the main wire, and a second throughput configured to receive one of them! of another connecting saw on the burden,
    Such items are well known and are often used where there is a need for a distance between the main wire of the crane and the load, and to more easily be able to fix and release the load from the main wire of a crane. In many cases, special tools are used, in which the item is to be raised. and from a mounting location, placed. An example! this can be a blade for a wind turbine that is placed and secured in an air tool, so as not to damage the surface of the blade during handling from the ground surface and to its mounting position on the wind turbine hub. When the blade is mounted in the correct position, the blade is released from the ceiling fan tool, which is then removed from the wing. However, the release procedure can be difficult and cause damage to the surface of the blade, provided it is not performed carefully and carefully. In this connection, it is to be assumed that the center of gravity of the lifting tool is changed in the same instant the wing is released from the wing due to the weight of the lifting gear, and in order to accommodate an angular rotation of the lifting tool, it will be necessary to move the lifting weight. against uncontrollable displacements of the lifting tool in relation to the mounted wing on the hub of the windmill, which may cause an undue mechanical impact on the wing, which in some cases will damage the surface of the wing. Thus, in order to control the movements of the lifting tool, it is very important that the operator of the crane can make sure that the main wire of the crane, in which the lifting tool is placed, is in a vertical position and thus does not form an angle with respect to the vertical. So far, this information has only been possible by visual inspection of the crane's main wire, and in the case of an angular deviation relative to the vertical, the operator of the crane has been able to make certain compensatory movements with the crane's outer arm or hook to bring the main wire into position. iodinated position. This work is time-consuming and not always easy to carry out, since the distance between the crane operator and the wire is often large (often about 100 m), and the crane wire can also be shaded by the wing, the operator owls an employee to! have the opportunity to move slightly around the moil, since it is not sufficient to see the ceiling wire from only one angle, so a certain margin of error must be mated, which may cause adverse mechanical effects of the moileving surface. So far, the crane hook has been moved in so far as the crane wire has visually appeared to be vertical or one has given the crane operator information about an approx. moving the ceiling point (eg "move the hook about 0.5m longitudinally of the wing"). In both procedures there are some sources of error. Compared to giving the crane operator information about a given crane hook movement of, for example, 0.6m in a given direction, this operation is difficult to carry out, as the move is often a combination of both having to hook and boom the crane. The crane operator can therefore have even a great deal of difficulty in performing the crane hook baths in relation to ten! direction and direction.
    The above scenario also occurs when you go! remove a blade from the mole, for example in connection with the service of a windmill. For example, if the center of mass center position is different for unladen and loaded lifting tools, respectively, the lifting point's lifting point should be shifted after the lifting tool is attached to the wing and for the lifting tool, with wing, to be pulled by hub. again it is necessary to verify the crane wire is vertical for the blade being pulled out of the hub.
    Accordingly, it is the object of the invention to provide a device which allows an operator and / or a crane supervisor of a current crane to at any time be able to clear / paint the angle between the ceiling wire and the vertical.
    This form is achieved by a ceiling bracket for mounting between the main wire on a crane and a load suspended in the main wire, where the main wire's Isengdax axis is defined as the Y-axis and a plane on the Y-axis is defined by the X-axis and Z-axis respectively. . wherein the ceiling bracket comprises an elongated body with a first throughput configured to receive a portion of a first connecting link staring in connection with the main wire, and a second throughput configured to receive a portion of a second connecting link on the load which is characterized in that the second through-out outlet comprises a spherical bearing configured to support the second connecting link, and the flat-like body adjacent to the spherical saw comprises a measuring instrument with a signal for recording the vinkien imeliem loft wire and vertical , where the signal generator is configured to send a signal containing painting results for visualization on an external device placed by the crane operator and / or to a crane supervisor informing the crane operator of what operations to take! carried out with the crane.
    In this way it is achieved that the crane operator / crane supervisor can quickly and easily form an overview of whether the crane's main wire forms a winder with the guide, without having to move outside the cab of the crane.
    Without sacrificing other modes and embodiments, the signal encoder instrument can be constructed by an inclinometer that paints angular rotations relative to the horizontal about the X axis and allows the signal transmitter to transmit relevant signals to the external unit. In a further embodiment of the lifting bracket according to the invention, the instrument instrument with signal encoder can be formed by an inclinometer which measures angular rotations with respect to the horizontal about the Z axis, and via the encoder transmits relevant signals thereto to the external unit, alternatively by transmitting two relevant independent signals regarding angular rotations relative to the horizontal about the X-axis and Z-axis, respectively, to the external unit.
    The invention is explained in more detail below with reference to the drawings, in which; FIG. 1 is a side elevational view of a lifting tool for use in positioning a blade to a windmill suspended in a wreath's main wire via a ceiling bracket according to the invention; FIG. 2 is a detail view of the ceiling bracket according to the invention; FIG. Figure 3 is a detail view of the ceiling bracket according to the invention, seen from above; Figure 4 is an end view of the ceiling tool for use in positioning a blade to a windmill, suspended in a wreath's main wire via a ceiling bracket according to the invention, where there is an angular deviation between the main wire and the vertical; 5 shows the same as FIG. 4 but in detail; and FIG. 6 shows where the angular position of the crane's main wire relative to the vertical is shown on a display near the crane operator and / or crane supervisor. In FIG. 1 is a side view of lifting tool 2 for use in positioning a blade 4 to a windmill, suspended in a wreath's main wire 6 via an elevator cover 8 according to the invention. The dashed line 10 illustrates the vertical, y-axis, and the dashed line 12 illustrates the orientation of the crane's main wire 6, and it is thus seen that the crane's main wire forms an angle A, relative to the vertical. In FIG. 1, the z axis is also illustrated by the dotted line 11.
    FIG. 2 and FIG. 3 is a detail view of the lifting bracket 8 according to the invention, seen from different angles. The ceiling bracket 8 comprises a flat-like body 14 with a first through-out outlet 18 configured to receive a portion 17 of a first connecting link 19 (cf. Fig. 4 and Fig. 5) staring in connection with the main wire 6, and another through outlet 18 configured to support a portion of a second connector 20 on the load 2, suspended in the main wire 8. In FIG. 4 and FIG. 5, which is a single debill of the power tool 2 for use in positioning a blade 4 to a windmill, suspended in a main wire 6 on a crane, via a ceiling bracket 8 according to the invention, where there is an angular deviation A the main wire 6 and vertical 10th
    The second through outlet 18 comprises a spherical bed 22 configured to accommodate a portion of the second connector 20, and the flat-like body 14 opposite the spherical bed 22 comprises a housing 24 which, for illustration's sake, is shown diagonally open in FIG. 2 and in particular in FIG. 3, in which is arranged a painting instrument 28 with signal encoder 28, where the painting instrument 26 detects the angle A between the crane's main wire 6 and vertical 10, where the signal encoder 28 is configured to send a signal containing measurement results to a PLC, from which the signal is sent to visualization on an external unit 30, (cf. Fig. 6), located by the crane operator and / or crane supervisor.
    The painting instrument 26 with signal sensor 28 is constructed in the illustrated embodiment of an inclinometer which measures angular rotations with respect to the horizontal about the X-axis 13 and Z-axis 11, and via the signal sensor 28 transmits relevant signals thereto to the external unit 30. In FIG. 6, the external unit 30, which shows on a screen 31 the orientation of the crane's main wire 6 with respect to the vertical (y-axis), detected by means of the maize instrument 26 with the signal transmitter 28, on the ceiling bracket 8 according to the invention. The screen may advantageously be located in the crane's cab (not shown) and / or with the crane supervisor, so that the crane operator and / or crane supervisor can, as needed, orientate himself to the vertical of the crane.
    The dot 32 in the center of the screen 31 represents the vertical 10, and the dot 34 indicates the current orientation / angle of the main wire 6 relative to the vertical (10).
    It will be possible to connect the external unit 30 with an overall control system / control unit, to which data concerning the orientation of the main wire with respect to vertical 10, for example in connection with the mounting of a blade on a wind turbine, is performed and where the control of the gripper arms of the ceiling tool only activates when the orientation of the main wire is correct in relation to the center of mass of the unloaded ceiling tool.
    Finally, it should be stated that the inventor has recognized that for detecting the angle between the main wire 6 and vertical 10, other useful painting instruments than the indicated inclinometer exist, but this does not change the inventive aspect which consists in a providing a quick overview of the orientation of a wreath's head wire 6 relative to vertical, using a ceiling bracket according to the invention.
